IMPROVED MACHINE lFOR MAKING BRUSHES. Y

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: A

Be it known 'that I, A. M. XVHITE, of Thompsonville, in the county of Windham, and State of Connectient, have invented a new Improvement in Machine for Making Brushes; and I do hereby declare the foli lowing, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact 'description of the same, and which said drawings constitute part of this specification, and represent in Figure l, a side View;

Figures 2 and 3, the adjustment for making the movement of the table automatic; and in Figures 4, 5, 6, 7, to illustrate 'the operation.

This invention relates to an improvement in the machine for making brushes, for which a patent was granted to me, bearingjdate December 22, 1868, the object being theadaptation of the machine to making brushes of irregular form, or in which the tufts are set atl different angles. To this end,

The invention consists in combining with a device for forming and .setting the tufts, a mechanism for adjusting the body of the brush, so that the tufts will be set therein at the properangle.

To enable others to construct and use my improvement, I'will fully describe the same, as illustrated in the accompanying drawings.

The apparatus is first applied to a machine for boring the brush-back.

A is the rest, or base of the adjustable apparatus.

B, a vertical spindle, made adjustable in the said base, so as to be raised or lowered in any convenient manner, the upper end of the said spindle being of a,

ball-shape, as denoted in broken lines, figs. 1 and 2, and to this ball a table or plate, C, is 'attached` so as to turn freely on the said ball.

In dg. 1, the table is represented as swinging up or down, and to the right or left, as denoted in blue and red, and is guided by a segment, D, fixed to the table, and passing through the spindle.

vThe table is adjusted to any desired point or inclination, and then secured by means ofthe segment.

Centrally on the ball of the spindle is formed a point, a, which passes up through the table for the purpose of adjusting the brush-body for boring, or setting the tufts.

A holder, E, is frmed, as seen in fig. into which the .blank or body ofthe brush is securely fixed.

The opposite side of the said holder E, is perforated or indented in a form corresponding to the brush to be made, each indentation representing the position of the holes to be bored, and the tufts to be set in the body of the brush, as represented in dg. et, and in section in fig. 5, the brush-back being `tted to the holder, as seen in iig. 7.

The table is inclined to the position required, say for setting the outer row of tufts; then the, brushholder is set on to the table so that the point a will enter one of the perfor-ations, or indentations in the back of the holder, as seen in fig. 6; then by the boring-apparatus the brush-backF is bored at that point, and upon an inclination corresponding to the inclina- `tion of the table C, the outer row, or as many holes are bored in the back of the brush as are desired at this inclination; then, for a dil'erent inclination, the table is newly set, and thus any desired inclination of the perforations maybe made inthe brush-back; then, in like manner, the brush-back upon the same holder, or another correspond'ing, is placed beneath the tuftsetter, and the tufts inserted in like manner as the holes were bored, the position being governed by the point a. u

In figs. 2 and 3, a universal adjustment is shown by the use of two segments, G and'H,vso as to incline the table inv any desired directioinso that an irregular or curved surface of the brush may be set, by adjusting the table by means of the two segments, so as to properly present the brush to the boring, or settingapparatus.

Instead of adjusting the table as first described, and shown in fig. 1, the segments may each be worked by a worm, as denoted in fig. 2, and the worms may be operated directly from the mechanism-ofl the machine, so that, co-operating with the machine, the irregular form or inclined tufts may be set into the brush automatically guided.

The connection oi' this apparatus with the machine for making it so automatic, will be readily conceived by persons skilled in the use of such machines, it

being simply a chain of gears giving to the worms,

respectively, and at the proper time, the necessary revolution to turn the table.

The spindle B is made adjustable vertically, so as to raise or lower the table, as may be required, for boring or tufting the back.

Having fully described my invention,

What I claim as new and useful, and desire to secure by Letters Patent, is I 1. The table C, arranged upon a universal joint on the spindle B, so as to be adjusted to present the brush-back to the bit, or tufting-apparatus, substantially in the manner and for the purpose set forth.

2. The holder E, perforated or indented corresponds ing to the design of the brush to be produced, so as to be adjusted upon the point a, on the table, substantially as and for the purpose set forth.
